Attachment device of tower crane lattice form

Abstract

The invention discloses an attachment device of a tower crane lattice form, and the device comprises a draw bar, wherein one end of the draw bar is provided with a first mounting part connected with the tower crane body; the other end of the draw bar is provided with a second mounting part connected with a building structure; the second mounting part comprises a front bracket and a rear bracket; and the front bracket and the rear bracket are connected by virtue of a two-start worm. The attachment device is characterized in that the contact surface of the front bracket, the rear bracket and the building structure is provided with a rubber plate; and parts of the rubber plate are embedded in the front bracket and the front bracket. The attachment device has the advantage of long service life.

Description

technical field [0001] The invention relates to a tower crane attachment device, in particular to a tower crane lattice attachment device. Background technique [0002] At present, with the rapid development of my country's economy, the scale of construction is also expanding. As we all know, the self-elevating tower crane is an important construction machine on the construction site, and it is responsible for important vertical and horizontal transportation tasks. It is fixed at a distance from the building As the height of the building increases, it will rise accordingly. When its height exceeds the specified independent height, it must be connected to the building structure through attachment devices at certain distances to ensure that the tower body stiffness and stability.

[0003] The Chinese patent authorization announcement number is CN201747052U, and the authorization announcement date is February 16, 2011. The invention patent discloses a new type of non-destructive tight hoop attachment device for climbing formwork and climbing frames, which is used for no damage to building structures by climbing formwork and climbing frames. Attached and fixed, it is composed of a front bracket, a rear bracket, a double-ended screw, a large beam, a small beam, a wall seat, and a fixing sleeve. Although the attachment device of this invention is directly surrounded by the structure when in use, it does not need to modify and repair the structure itself. can be destroyed and reused; at the same time, the attachment device of this invention is adjusted by replacing the connecting screw, so that it can be adapted to various needs of different structural forms; the attachment device itself also has the advantages of simple structure and high strength, but the attachment device of this invention It is in rigid contact with the building structure, and there is no reasonable shrinkage gap between them. When the tower crane shakes slightly due to changes in the external environment, the attachment device wears seriously, making its service life shorter
